4 Natural Immune System Supplements

It’s that time of year when sniffles become more common and we can find ourselves feeling a little under the weather. So, we thought it was the perfect time to share with you our favourite natural supplements for immune system support.


Camu-Camu is a small tree native to the Amazon Rainforest. It produces cherry-like fruit containing the highest source of vitamin C in any food - 30 times the amount found in an orange! The benefits of vitamin C to the immune system are well-known, thanks to its potent levels of protective antioxidants. A natural vitamin C supplement like Camu-Camu is assimilated into the body much more quickly than synthesised vitamin C, and it’s more gentle on the stomach, too.

Pau d’Arco

If you’re looking for a natural supplement to boost your immune system, look no further than antioxidant-rich Pau d’Arco. Available in tea or capsule form, the bark from the Pau d’Arco tree has been used by Rainforest tribes for over two thousand years to support the body’s natural defences. 


Samento is a special variety of the Peruvian herb Cat’s Claw, that doesn’t contain Tetracyclic Oxindole Alkaloids (TOAs). It’s been used for over two thousand years by Rainforest tribes including the Asháninka people, who have the longest recorded history of use of the herb. Samento can help to strengthen the immune system whilst also helping to maintain flexible joints. In its liquid form, Samento should be taken twice daily, building up gradually from one drop to 20.


Pinella is an extract from the bark of the Pimpinella Anisum tree, commonly known as Anise (which is where Aniseed comes from). This extract helps to support the immune system whilst also contributing towards healthy digestion and healthy lactation in women. In its liquid form, 5-10 drops of Pinella can be taken 3-4 times per day.

As with all natural supplements, consult your doctor before trying them if you’re currently taking any other medication, have a long-term health condition or are pregnant/breastfeeding.
